高压架空输电线路的故障测距方法

对高压架空输电线路进行准确的故障测距是保证电力系统安全稳定运行的有效途径之一。为此，章比较全面的介绍了国内外在此方面的发展历程和研究现状。根据各测距算法采用的原理不同，将现有的各种测距算法分为行波测距、单端测距和双测距三类，然后逐类对各种算法的理论基础和应用条件上进行了分析、对比和讨论，并在此基础上总结得出了各测距算法的优点及存在的问题，指出了每种测距算法的适用范围和应用局限性。最后，对高压架空

A FAULT LOCATION METHOD FOR OVERHEAD HIGH VOLTAGE POWER TRANSMISSION LINES

Because the accurate fault location for high voltage transmission line plays increasingly important role in power system, the development and general situation of the research in this field in China and in other countries is reviewed in this paper. All the existing algorithms can be classified into three main methods: traveling wave location, single terminal location and two terminal location, the principle and application condition of each algorithm are presented and discussed. Base on the analysis and comparison of each algorithm, the corresponding merits and application limitation are concluded. At last, the prospects in fault location are described.
